Does anyone know how far over a certain mileage you can go before it voids the warranty? I'm asking because my car goes in Monday for it's 10k service, but I hit 10k officially this morning. I assume I've got a couple hundred miles leeway, but I couldn't find it in the manual (I might be blind, though). Is it +/- 500 miles? I thought I remembered reading that somewhere...

I have been told by some dealers it really does not matter as long as you get it in within 1000 miles. And I have been told it doesn't matter at all.

If you go over, just buy the oil and filter and do it yourself and just write down what you want as to when you changed it. The oil change is the one that really matters the most.

It doesn't matter if you're within a few hundred miles. They can't expect you to bring it in at 10000 miles on the nose.

Besides, we technically get 'til 7500 miles to do oil changes, so they certainly won't void your warranty if you're a few hundred miles past 5000.

To the best of my knowledge, the 10K mile service has nothing to do with the car's overall general warranty. Manufacturer "suggested" service intervals are typically just that: suggested. In fact, they tend to be somewhat liberal when they refer to oil changes.

Maybe Mazda offers a separate 10K warranty on its cars...but I'm not familiar with it.

It's not like your warranty disappears if you don't take the car to the dealership for the 10k service. I do all the work on my own vehicles, and while I'm responsible if I screw something up (forget to put in oil, put the wrong oil in the differential, etc), it's valid service so mazda must honor their warranty if my car breaks.

Plus, I'd imagine the 10k service is mostly a joke, anyways. I haven't looked it up, but somehow I'd guess it includes checking your fluid levels, changing your oil and air filter, and rotating your tires.

Well, if they could prove that you never changed your oil and something went wrong with the engine because of that, your warranty would be shot, I suppose. So, I assume that you need to at least loosely follow the maintenance schedule in the manual.
